IMPROVED CHAIR-SEAT.

Specification forming part of Letters Patent No. 55,605, dated June 19,1866.

To all whom it may concern:

Be it known that I, ALANSON BINGHAM, of Surry, in the county ot'Cheshire and State of N ew Hampshire, have invented certain Improvementsin Chairs, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart ot' this specification, in Which- Figure l is a plan of the seat ofa chair attached to its frame according to my improved method. Fig. 2 isa section on the line a: x of Fig. l. Figs. 3, 4, 5 and 6 are enlargedsections, representing my improved method of attaching the seat to itsframe, together with niodications of the same.

Nly invention relates to certainy improvements in chairs for whichLetters Patent ot' the United States were granted to myself and OsmoreA. Bingham, on the lith day of April, A. D. 1866; and myinventiononsists in attachin g a seat composed of a single thickness oi'strips of oak, ash, or other suitable wooden material to a frameprovided with slits, or slits and grooves, into which the ends of thestrips are passed and securely confined to the frame.

To enable others skilled inthe art to understand and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, Arepresents the pieces composing the frame of aseat of a chair, secured to each other in any well-known manner.Extending through from the top to the bottoni ot' each piece A of theframe are formed two narrow slits or openings, a b, within which arepassed the ends of the strips c of the material from which the seat isto be made, the method of weaving which will now be described.

The end of a strip of the material is first passed down through the slita, in either the back or front piece, A, of the frame, and at a shortdistance from the corner thereof, when the end of the strip is bent upthrough the inner slit, b, where it may be cut oft' flush with the upperside oi' the piece, as seen at d, Fig. 3, or be drawn up and laid overthe top of the piece, so as to extend to its inner edge, as seen at e,Fig. 4C, the portion thus laid over being pressed down snugly in placeby the strip, when carried over to the opposite piece, to which it issecured in a manner similar to that just described, the strip beingdrawn tightly before being cut off at either of the points abovementioned. Each strip, after being laid on, is pressed up by hand towardthe center ot1 the front and back piece, whereby they are still furthertightened, the distance between the slits increasing from the sides tothe center of the front and back pieces'of the frame.

The strips laid on in this direction constitute the Warp. (See redarrow.)

The strips constituting the filling (see blue arrow) are now enteredwithin the slits of one of the side pieces, A, near the frontpiece, andare run alternately over and under each strip composing the warp, when,after being cut oft', they are pushed up toward the front piece, wherethey are securely locked in place, the distance between the slitsincreasing from the back to the front piece, whereby the strips aredrawn tightly as they are pushed along therein, as described.

j' are strips which may be set into the slits a b after the seat iswoven, for the purpose of V wedging the ends of the warp and tillin gand keeping them from drawing out.

Each piece A is provided with a screw, 7, which enters from the insideand passes into the piece a sufficient distance to draw the parts nearerto each other, thereby holding the strips tightly in place and givin gadditional stiffness to the seat.

Instead of forming two slits a, b, Within each piece A of the frame, oneof the slits may be omitted, and a groove, g, (on the inside or outsideofthe other slit,) may be substituted therefor, and the ends of thestrips secured therein, as shown in Figs. 5 and 6, without departingfrom the spirit of my invention.

If desired, cement may be used in the groove g to hold the ends of thestrips more securely. v

A seat constructed and attached to its frame in the manner abovedescribed is more durable and can be furnished at a less cost than thosemade in the ordinary way.

What I claim as my invention, and desire to secure by Letters Patent,is-

Attaching a seat composed of a single thickness of strips 'of oak, ash,or other suitable wooden material to a frame by means of slits, or slitsand grooves, substantially as described.
